Our club does an Iron Brewer style competition twice a year. Club members think of random ingredients and write each them down on a separate piece of paper. All the pieces of paper are tossed into a hat. Three ingredients are pulled from the hat randomly during a meeting or at club party. Those participating in the competition are required to brew a beer with those three ingredients. They can brew any beer they want, but they have to use those three ingredients in the beer. For example, our most recent beers had to use belgian saison yeast, oak, and special B. We give brewers two months to brew the beer.
At judging time, all of the brewers get together. One by one, each brewer gets up, severs their beer everyone and discusses what they were trying to accomplish. Each person then judges the beer based on flavor and use of the chosen ingredients and gives the beer a score. The scores of each beer are tallied at the end. The winner of the competition gets a goofy trophy until the next competition.
